Abstract: Disclosed is a method for reconstructing a Bravais lattice of a crystal by using an electron diffraction pattern. The method comprises the following steps: step 1): recording a zone axis electron diffraction pattern of a crystal to be tested, and obtaining a zone axis electron diffraction pattern containing high-order Laue diffraction; step 2): measuring a two-dimensional primitive cell; step 3): measuring a high-order Laue diffraction ring; step 4): measuring a high-order Laue diffraction point; step 5): reconstructing a three-dimensional reciprocal primitive cell; step 6): transforming the reciprocal primitive cell obtained in step 5) into a direct lattice; step 7): carrying out reduction processing; and step 8): transforming a Niggli-reduced cell into a Bravais lattice. By means of the method, the lattice type and the lattice constant of a crystal to be tested can be obtained through analysis by using only one zone axis electron diffraction pattern containing high-order Laue diffraction points; and during an actual electron microscope experiment and actual data analysis, the method can greatly reduce the amount of work required for an experiment and analysis.

Filed: 2019-08-15
Abstract: A method and apparatus of Inter prediction for video coding are disclosed. According to one method, a sub-block motion vector prediction (MVP) mode is turned off for small size coding units (CUs). In another method, if the neighbouring reference block for a current coding unit (CU) is in a root CU region, the neighbouring reference block is not used to derive a Merge candidate or a modified neighbouring reference block on the shared boundary of the root CU is used to derive the Merge candidate for the current block. In yet another method, a shared sub-block Merge candidate list is derived for sub-CUs within a root CU region or an MER (Merge estimation region). If a neighbouring reference block is within the same MER as a current sub-CU, the neighbouring reference block is not used for deriving a candidate for the shared sub-CU Merge list.
